IMPROVEMENT IN lIiATH-IillIl-LC2IEIIN'IE2.

The Schedule referred to in these Letters Patent and makingi part of the same.

To whom 'it may concern: i

Beit known that I, JAooBVDoBBINs, of Litchfield,

`in the county of Hillsdale, andState of Michigan, have invented anew and usefulImprovement in vLath-Cutting Machines; and ,I` do declare that the following is a 'true and accurate description thereof, reference being "had to the accompanying drawings, and to the letters reon, and being a part of this `forcing the bolt in contact with two pairs of stationary knives, each` pair of' which 4ents alath from the bolt iu i its pas,sag\y through the machine; also, in the peculiar shown and-set forth..

In the drawings i Arepresents `a proper by a feed-table, B.

. C isa driving-shaft, journalled in `properbearings at the front-and rear endsof themachine frame D is a spur-gear, secured tothe drivingshaft, outside of the rear bearings, and engages with the larger arrangement o1n its partsyas hereinafter more fully frame, surmounted in front spur-'wheels E and 1" on the roll-shafts F and F', jonrnalled atfeach side and'below it, in the cross-beam of the frame at the rear end of themachine,

" The shafts F and F' project forward into the frame ofthe feed-table, and are provided with the corrugated `rollers G and G', for forming the -under feed, the roller G being provided with a collar or flange, H, which guides the inner edge ot the bolt in its passage, and, being set inward from the inner knife, the thickness of `the inner lath by it is ganged tothe cut of said knife.

Fand I'are the shafts carrying the upper feed-rollers J and J', and `which are journalled at their rear end to the cross-beam of the frame, where they receive motion bytheir spur-gears, K and K', meshing' with similar gears, L and L', on the shafts F and E'.

Said gears L and L being of the same diameter as the gears K and di', all of their shaft-sand rollers revolve at the same speed.'

shafts of the feedroll`ers,`for the reason which I shall presently explain.` i i l The front bearings of the upper roller shafts are -in an elastic semi-elliptic yoke, N, secured to the machine frame behind the feed-table, so that in ease a bolt ot greater than the usual thickness be fed t6 the rollers, they will rise up and ease the bolt in its passage with-4 out choking the` rollers, as would be the case were they journalled in a rigid frame.

O and O' are angular knives,` securely bolted to the frame, Ybetween the feed-rollers, and are set forward from the guiding-gauge H the thickness of a lath, and

Ninclined ou their cutting-edges, so as to give drawing onton the bolt.

The lower knife O rst cuts the lath one-half through the bolt, while the upper and rear knife O completes the division. 4 y l? and P are knives, similarly arranged, but so secured to the frame that they will out a second lath from the bolt in its passage through the machine.

The spiked drum M, revolving with greater speed than the traiirof feed-rollers, tends to assist them Vin carrying the bolt along by the spikes on its periphery cutting into the surface of' the bolt. It also serves as a. carrier' iu returning the bolt after the laths have been cut from it, as I will presently explain.

Q are ordinary carrying-rollers, journalled into the feed-table, the discharge-end of which is inclined, as shown.

R andl R' are spiked drums, revolving' in 'proper bearings at the top and bottom of the inclined apron of lthe feed-table, and are rotated by belt c' from apulley on the shaft C, to the pulley 1" ofthe drum R, and from which pulleyy a second belt, 0', transmits the motion to the pulley l`r"' on the drum R.

XVhen the bolt has had the latlis 'cut from itaud reaches the spiked drums It and R', and rests on their upper surfaces, it will be' moved back by them tow-ami the knives, when theope'rator directs its right end yover the spiked drum M, which delivers it at the proper point to be again fed to the knives, to guide ythe bolt to its proper position in re-entering the feed-rollers.

A-rotating rest, S, is pivoted tothe back-frame of the feed-table, so that when the bolt drops on it, it will he guided directly to' its place, when it vwill be automatically sent. forward by the vibrating lever T, piv-` oted at its lower end to the legs of the frame, and weighted on its inner side to keep it toward the feed-y rolls.

When the-bolt is brought back from the drum M, its right end is brought to the shoulder t, at the top fof the vibrating lever l, which is carried back until 'lhe drivin g-sh aft G is extended over the feed-table, y and has secured to its end the spiked drum M, which, with its shaft, `revolves at a higher speed than` do thev the other end of the bolt `has passed the centre of the rotatingrest and dropped ou thefeed-table, when the weight U on the lever will move the bolt along to the rollers, or materially assist the operator in so doing.

'lo cause the bolt to be automatically carried to the feed-rollers, the carrying-roller Q, under the rotating rest S, may he rotated hy a crossedbelt from apnllf-iy on the feeding-shaft C, if desired, in which case its What I claim as my invention, and desire to secure sha-ft should project far enough behind the frame of by Letters Patent, isthe feed-table to receive a pulley for that purpose.

This device is equally adapted to cutting lath with the vibrating lever T, constructed and operating as saws. In this case the knives are dispensed with, and and. for the purpose aforesaid. one or more saws are attached to an additional shaft Witnesses: JACOB DOBBINS. under the' drive-shaft C, and propelled by it by means JOHN 'I'.
